The Helium-Neon Laser is used for diagnostics on the Ruby laser and others. The
higher the power output of the laser the better, get one around 5mw, anything
higher than this poses a great risk to your vision. Also make sure that it comes
with a power supply running from 120V AC, otherwise you'll find yourself building
a HeNe power supply essentially blind folded. If you have any questions on selecting
your heat HeNe laser you can contact me here.
